- Charles Steinmetz, August 1904 - Charles Steinmetz excelled at applying mathematical theory and scientific methods to practical engineering, helping define the role of "scientist-engineer" in the American electrical industry. Steinmetz developed important theories on alternating currents, conducted breakthrough experiments on power loss, and authored a number of influential textbooks. His innovations shaped the electrical engineering profession and improved and expanded electrical distribution systems.

- We Hand You a Hint: The Hemco Twin-Lite is Made of Condensite, circa 1915 - Chemically synthetic plastics were developed in the early 1900s to replace shellac and hard rubber -- naturally derived substances increasingly in demand for various industrial applications. The Condensite Company of America formed in 1910 to sell a new material first developed at Thomas Edison's West Orange laboratory for phonograph records. Durable and nonconductive, Condensite was well suited for electrical products.

- Reactance Coil, Used at Hammond Radio Research Laboratory, 1915-1920 - John Hays Hammond, Jr., is considered "the father of radio control." In 1926, he built a medieval-inspired castle in Gloucester, Massachusetts, as his home and research laboratory. With 400 patents to his name, Hammond developed radio control, autopilot function, and targeted missile detonation. A reactance coil is an inductor, blocking high-frequency AC power, allowing low-frequency DC power to pass.

- Eickemeyer Dynamo, Used by the Haxton Canning Company, 1889 - Rudolf Eickemeyer developed his "ironclad" dynamo in the 1880s. The unique method of construction--its heavy iron field coil construction and iron sheathing--gave the dynamo its nickname. It was compact, rugged and efficient, though the ironclad design made it difficult to cool. This dynamo supplied power for the lighting system and small motors at the Haxton Canning Company in Oakfield, New York, for 15 years.
